Quasi Delict is a French legal term used in some civil law jurisdictions. It refers to a negligent act or omission which causes harm or damage to the person or property of another, and thus exposes a person to civil liability as if the act or omission was intentional. It is a residuary category of private wrongs, characterized by either vicarious or strict liability. In quasi delicts the law creates a liability though the defendant may not in fact be to blame.
A quasi-delict is a wrong which occurs unintentionally, as a result of something like negligence, where as a true delict requires intentional action. Thus, someone who commits murder has committed a delict, while manslaughter would be an example of a quasi-delict.
